React - 转换 HTML 脚本标签以异步加载 SDK

Question

Currently I'm trying to add snapchat to a site through their SDK

my current attempt, can't figure out how to convert their Dom script into a function to be called when my component is loaded:

export function snapchatSDK() {
  return new Promise(resolve => {
    const script = document.createElement('script');
    script.src = 'https://sdk.snapkit.com/js/v1/create.js';
    document.head.append(script);
  });

}

class Platforms extends React.Component {

  componentDidMount() {
    snapchatSDK();
  }

render() {
    return (
      <div>
      <p> Share on Social Media Platforms</p>
      <h4>Snapchat<h4>
       <button 
         className="snapchat-creative-kit-share"
         data-share-url= urlTobeShared()
          >
         Share me 
       </button>

       <h4>Twitter<h4>
       <button>
         Share me 
       </button>

      <h4>Reddit<h4>
       <button>
         Share me 
       </button>
      </div>
    );
  }
}

Here is a link to the doc's as well: snap doc

Answer 1

Your example doesn't make it very clear what you're trying to accomplish, but maybe one of these will help you figure it out?

Option 1

Try the unoffical snapchat npm package . (no idea if the package does what you need, buy maybe you haven't seen it yet?)

Option 2

Load the script in your HTML

<script src="https://sdk.snapkit.com/js/v1/create.js" />
<script src="/path/to/your/bundle.js" />

If loaded before your components mount, it should pick up your HTML and do whatever it does

Option 3

Maybe try setting async = false on the script:

const script = document.createElement('script');
script.src = 'https://sdk.snapkit.com/js/v1/create.js';
script.async = false
document.head.append(script);

Please see this article and this SO post . Key takeaway is:

Scripts that are dynamically created and added to the document are async by default

Answer 2

I think that the main issue is how you are trying to load the script dynamically. I am guessing that is what you want to do. If so, there are several more steps. Here is a link to a comparative example that goes through some of them: https://www.newline.co/fullstack-react/articles/Declaratively_loading_JS_libraries

Answer 3

If you are using parcel2 or webpack4 (or create-react-app) then you could use dynamic import and most importantly without this issue

However, the code is simple

    import("https://sdk.snapkit.com/js/v1/create.js").then(_snap =>
      setSnap(_snap)
    );

if you are facing that issue you could use

    import(/* webpackIgnore: true */ "https://sdk.snapkit.com/js/v1/create.js").then(
      _snap => setSnap(_snap)
    );
